| Note: | 8/19/1985 Summary of Steamvalve Geyser: It seems to erupt every 3 ½ to 4 hours (being the interval). The eruption is preceded by bubbling in the pool. The eruption is very much like a small Equinus [sic] but with mucky water. The height of it goes up to 10-12 feet or so, with the eruption going for 5 or 6 minutes. It takes about 2 minutes to overflow and after the eruption there is a rapid drain of 2/3 of the pool, which takes about 1 ½ minutes. Then the drain is very, very slow if at all. It is very much like a small Equinus. [sic] |
